本文通过一种新的初始化方法把Mumford-Shah模型和水平集中的窄带解法结合在一起。

In each step of iteration, the new segmentation model only deals with the data in a narrow band instead of the whole image.

窄带Mumford-Shad模型把分割计算限制在窄带范围内，避免了大量的计算，但取得了与原始的Mumford-Shah模型相同的分割效果。

The use of genetic algorithms and iterative threshold method of image segmentation.

详细说明：使用遗传算法和迭代阈值的方法实现图像分割。

Experimental results demonstrate the efficiency of the improved algorithm in shot segmentation and key frame extraction.

实验结果表明了改进算法在镜头分割和关键帧提取方面的有效性。

Then key frame extraction will be carried out after shot segmentation to describe main content of shot.

视频分割为镜头后，下一步的工作就是进行关键帧提取，用以描述镜头的主要内容。

Four types of key video frame segmentation were discussed in this thesis, according to different scene type.

本文采用四种分割方式对视频关键帧进行区域划分，每种分割方式对应不同的视频帧类型，并由此进一步判定镜头类型。

Finally, the label with the greatest probability is assigned to each unlabeled vertex,and image segmentation boundaries are obtained by expanding the labeled backbone graph to the original image.

该算法用图像的高频子带信息优化了Laplace图构造，并用争议区域的进一步划分取代了Random-Walk中直接将最大到达概率所在的标签赋给待标定数据的方法。

Study of segmentation of surveillance objects with motionThe camera noise statistical characteristic is approximated as Gauss or Laplace distribution, then an error probability is set and a threshold is determined. According to the hypothesis test theory, a constructed statistic can judge whether an object is moved or not.

二、以运动物体作为监控对象的分割研究将噪声分布近似为Gauss分布或Laplace分布，再设定误判概率进而确定一个阈值就可以利用假设检验的思想，构成统计量对不同对象判断其运动与否。
